Method Of Classification For Multisource Data In Remote Sensing Based On Interval-Vaiued Probabilities, Hakil Kim, Philip H. Swain Jul 1990

Method Of Classification For Multisource Data In Remote Sensing Based On Interval-Vaiued Probabilities, Hakil Kim, Philip H. Swain

Department of Electrical and Computer Engineering Technical Reports

This work was supported by NASA Grant No. NAGW-925 “Earth Observation Research - Using Multistage EOS-Iike Data” (Principal lnvestigators: David A. Landgrebe and Chris Johannsen). The Anderson River SAR/MSS data set was acquired, preprocessed, and loaned to us by the Canada Centre for Remote Sensing, Department of Energy Mines, and Resources, of the Government of Canada. The importance of utilizing multisource data in ground-cover^ classification lies in the fact that improvements in classification accuracy can be achieved at the expense of additional independent features provided by separate sensors. However, it should be recognized that information and knowledge from most available …

Adaptive Control Of Flexible Joint Robots Derived From Arm Energy Considerations, Shaheen Ahmad, Fouad Mrad Jun 1990

Adaptive Control Of Flexible Joint Robots Derived From Arm Energy Considerations, Shaheen Ahmad, Fouad Mrad

Department of Electrical and Computer Engineering Technical Reports

Almost all industrial robots exhibit joint flexibility due to mechanical compliance of their gear boxes. In this paper we outline the design of three controllers for flexible joint robots. Two of the three controllers are suitable for parameter adaptation, the candidate Lyapunov functions for these two controllers are derived from arm energy considerations. The desired actuator trajectory in a flexible joint robot is dependent not only on the desired kinematic trajectory of the link but also on the link dynamics. Unfortunately, link dynamic parameters are unknown in most cases, as a result the desired actuator trajectory is also unknown: To …
